Green is the hot topic these days, and the concept is having an impact on the way people think about datacenters. Companies around the world are announcing ways to save energy and reduce costs by buying new hardware and services. Yet, there is little guidance on how you can take action to control energy costs. In the past, electricity has been treated as an overhead expense, like the cost of space. But with rising power costs and issues regarding reliability, supply, and capacity, electricity requires its own specific strategy.
Projects regarding performance optimization and cost reduction are a part of everyday best practices in nearly every area of business. So why not treat energy cost in the same way?
As Information Technologies (IT) pros, many of us make decisions about the configuration and setup of servers, the specifications on the equipment our organizations purchase, and the requirements for datacenter upgrades and construction. We even provide early design input during application development. When it comes to these projects, we obviously have a golden opportunity to be green and influence the energy efficiency of any datacenter.
The first part of any strategy is to know your current energy usage. You need to know where your energy is used and by what specific equipment, as well as what usage is efficient and what is wasteful in the datacenter. Unfortunately, it’s rare to find power-consumption metering in place that can break down usage to a level where people can see the results of their actions. Most organizations typically only see a monthly power bill that rolls up consumption into an overall bottom line. This offers little incentive for saving energy since individuals never see the impact of their decisions, and there is no way for them to prove that their changes have actually saved energy.
One of the first issues people confront when considering a green datacenter initiative is whether they have executive support. For the purpose of the article, I am going to assume the answer is "not yet." Executive support requires a serious commitment that provides resources and budget for your initiative. And while there is a lot of talk about green datacenters, the reality is that there is still often a lack of serious support at the executive level. If you did already have such executive support, you would probably be running a green datacenter right now.
Still, even assuming you are not getting the support you need, there is a great deal you can do to push your green datacenter initiative forward. So how do you determine effective actions to take in achieving your goals? Fortunately, energy efficiency is not a new concept and there is a lot that IT pros can learn from other industries. […]
Anyway, for whichever direction you choose, planning an energy efficiency program for your datacenter will require collaboration across groups in IT. Until recently, the typical approach to planning IT solutions has been to ignore power costs early on during the design phase, focusing on the hardware and software being purchased, along with the labor and hosting costs of the solution. When power is buried in the overhead cost of running solutions in a datacenter, energy efficiency is a low priority. Exposing the actual power being consumed by solutions is the first critical step in changing the behavior of your organization.

The sentence in which "can" is used in the same sense as in "there is a great deal you can do to push your green datacenter initiative forward." is:
